Today, Apple posted a mysterious message at its website teasing an event for tomorrow involving iTunes. The message also features a clock which, presumably, is counting down until the event happens.

What could this announcement be? Could it be that a certain band is going to finally have their music for sale in iTunes? Or, could it mean the beginning of cloud storage where Apple can finally use that big data center they’ve built?

Obviously, speculation among the Apple interested press has started in earnest. Our friends at TUAW (Where I’m also a contributor, btw) have put up an impressive list of possibilities. Fortunately, we only have to wait until 7AM Pacific tomorrow to actually find out what all the fuss is about.

Until then, let the speculation continue. What do you guys think Apple will announce?
